ULTRASONIC THERAPY DEVICE

PROBLEM TO BE SOLVED: To provide an ultrasonic therapy device capable of enhancing the reliability of an ultrasonic therapy.SOLUTION: A plurality of pieces of reception information corresponding to a plurality of target focus positions are acquired by executing repeatedly the formation of a medical treatment beam and the acquisition of reception information, on which the sound pressure distribution of that medical treatment beam is reflected, while changing a target focus position. On the basis of a plurality of pieces of reception information, a map generating part 28 creates a map expressing the change in a sound pressure distribution for the changes in the target focus position.SELECTED DRAWING: Figure 1
